CULTIVATOR FOR LISTED CORN.

SPECIFICATION forming part of Letters Application tiled October 18, 1838.

To CLZZ whom, it 11m/y concern:

Be it known that I, HARLIN B. KING, a citizen of the United States, residing in Jackson township, Jewell county, Kansas, have invented certain new and useful Improvements in Corn-Cultivators, of which the following is a description.

Myinvention relates to an improvement in corn-cnltivators; and it consists in the coinbination of two runners, two rearwardly-inclined knives attached thereto, a supportingframe placed upon the runners, two disks, pivoted and jointed supports for the disks, levers for adjusting the height of the disks, and levers for moving the disks laterally, as will be more .fully described hereinafter.

Figure l is a plan view of my cultivator. Fig. 2 is a vertical section of the same.

A. represents two runners rigidly secured together at their top edges, and which run upon opposite sides of the rows ot growing corn. Secured to the lower edges of the runners, near their front ends, are the rearwardly-inclined knives or cutters B, which cut the weeds and grass between the rows, and which are turned upward at their outer ends, so as not to clog in :muddy or heavy soil. Secured upon the tops of the runners, and extending traine or hoard C, which is placed in front of the platform C', upon which the driver rides. To the outer ends of the traine C are pivoted the bars D, to which the disks G are journaled at their rear inner edges. These bars D are jointed at O, so as to have hoth a pivotal motion for adjusting the disks laterally in relation to each other and a vertical niotion for regulating the depth to which the disks shall cut.

Patent No. 401,177, dated April 9, 1889.

Serial No. 288,511, (No model.)

Pivoted at each end of the board C is a hand-lever, I, provided with a dog, L, to en gage with the ratchet N, and to which lever is attached a connecting-rod, .l which is loosely fastened at its rear end to the har D. By means of the lever the disk can be raised or lowered at will and supported in any desired position by the dog and ratchet. The disks can be lowered and raised and moved laterally, as shown in dotted lines, as may be desired.

At or near the center of the hoard C is a T- shaped lever, I), which is operated by a connecting-rod, Q, from the hand-lever P', provided with a dog and ratchet, and which is pivoted at its lower end to the side of one of the runners A. Extending from opposite ends of the lever P are the connecting-rods R, which are fastened at their outer ends to bars D, and hy means of which the hars carrying the disks G can he adj usted laterally to accommodate them to the width of the rows. Both hars being secured to the same lever, P, they are hoth operated at the same time.

Having thus described my invention, I claim- In a corn-cultivator, the combination of the runners, the board or frame placed thereon, the pivoted and jointed hars connected to opposite ends of the hoard, the disks connected to the hars, levers for operating the bars and disks vertically, levers for moving the bars and disks laterally, and cutters which extend from opposite sides of the runners, substantially as shown.

HARLIN B. KING.
